## jazzylj Group Title find the derivative of y with respect to x: one year ago one year ago

1. jazzylj Group Title

$y=1/x(x+1)(x+2)$

2. amorfide Group Title

|dw:1350454366994:dw| this?

3. jazzylj Group Title

sorry...1 is the numerator...everything else in the den.

4. amorfide Group Title

do you know the chain rule?

5. jazzylj Group Title

y=1/(x(x+1)(x+2))

6. jazzylj Group Title

I pretty much know nothing for my calc class. I just need to get through this assignment that's due tomorrow and then I start my sessions with my tutor...any help is greatly appreciated

7. Mimi_x3 Group Title

$\large \frac{1}{x(x+1)(x+2)}$

8. Mimi_x3 Group Title

well you can use the product rule or the quotient rule

9. Mimi_x3 Group Title

have you tried expanding it

10. jazzylj Group Title

So...1$\frac{ 1 }{ x ^{3}+3x ^{2}+2x}?$

11. amorfide Group Title

you could bring it to the top, so all the powers change signs to a negative

12. jazzylj Group Title

$y'=\frac{ -(3x ^{2}+6x+2) }{ x ^{2}(x ^{2}+3x+2)^{2} }..??? 13. jazzylj Group Title sorry...that's so ugly. I'll retype it. 14. jazzylj Group Title \[y'=\frac{ -(3x ^{2}+6x+2) }{ x ^{2}(x ^{2}+3x+2)^{2} }$
